FIELD OF THE INVENTION

The present invention relates to a modular cabinet and particularly to a modular cabinet or rack furniture that can be coupled and assembled in various fashions to form different combinations.

BACKGROUND OF THE INVENTION

Modular cabinets are known in the art. A wide variety of modular cabinets are available on the market. Among them the design adopted a frame structure is commonly deemed most reliable. On that structure modular elements are hung and fastened to the frame. The modular elements can be coupled and assembled through suitable means according to different functions (such as open or closed racks, drawers or the like) to form varying combinations. The frame provides steadiness during assembly. The frame also provides a basic structural specification. The modular elements can be interchanged and replaced as long as they conform to the structural specification. In order to achieve a desired mechanical firmness, the modular elements have to be fastened securely to the frame.

However, the structure of the aforesaid conventional modular cabinets often is too complicated and assembly and installation are quite difficult. They mostly require tools to aid assembly and installation. Moreover, the front side of the modular cabinet often is divided by transverse bracing racks to reinforce the steadiness. Hence the overall aesthetic appeal suffers.

German Patent Publication No. 4136307A1 discloses a rack system equipped with a support frame (referring to FIG. 9 of that patent). The support frame has a base board to seal the bottom thereof. The base board is slidable in the longitudinal direction of the support frame. There is a fixed ridge to provide radial protection. It also has an anchor tool on the support frame to protect the base board. There is a spacer on the base board to provide upright support and a desired spacing interval. The spacer is nailed or bonded to the support frame, or screwed on the support frame through bolts.

To position targeted elements on the frame at least the targeted elements at two ends have to be fastened through a fastening tool. This issue is not being explained in the patent specification.

Another European Patent Publication No. 0750869A1 discloses a rack structure which has a track and separable holding elements. The holding elements are engaged with a frame to anchor the base board. The track has a hook structure on the back side to hold a holding element. Thereby anchoring can be formed by surrounding. But one holding element can fasten only one base board or element, and cannot fasten a plurality of base boards or elements at the same time.

Yet another PCT Patent Publication WO2005/111328A1 discloses a structure which has one element fastened to a vertical frame through a connection element. It also can fasten only one element, and cannot fasten a plurality of elements at the same time.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a modular cabinet that can be constructed easily and rapidly by coupling fewer modular elements without using tools.

The modular cabinet according to the invention includes a plurality of elongated and parallel posts and a plurality of targeted elements stacking along the posts. The posts form a frame to hold the target elements that is preferably formed in an upright structure. The targeted elements can be directly stacked over one another or spaced from one another through a spacer element.

Each of the posts has a first coupling portion. Each targeted element has a plurality of second coupling portions slidably engaging with the first coupling portion. Each second coupling portion has a retaining element to form a positioning relationship with the first coupling portion. The first coupling portion also has a fixing element to anchor and support the targeted elements at two ends of the posts. Thereby all the targeted elements can be fastened to the posts.

According to the invention the targeted elements are hung on the first coupling of the posts by sliding and movable longitudinally on the posts. The targeted elements can be spaced from one another directly or through the spacer element and held in the longitudinal direction of the posts. Installation of the invention does not need any tools. The targeted element can be mounted through a distal end of the posts in the first coupling portion and moved to a desired elevation, and spaced form each other. The second coupling portion of the targeted element does not have to be mounted through the distal end of the post, but can be directly positioned through the spaced interval of the first coupling portion.

The second coupling portion of the targeted element has a desired length relative to the first coupling portion. By mating and engaging the first and second coupling portions, a desired strength is formed to prevent the posts of the frame from tilting.

The post also has a fixing element installed on the distal end to prevent the stacking targeted elements from slipping out from the posts so that that all the installed targeted elements can be held securely on the posts.

In principle the posts can be held on sides walls of targeted elements at any positions desired. However, the preferably installation locations are corners of the targeted elements, while the side walls of the targeted elements can serve ornamental purpose. In general the posts located at the lateral sides of modular cabinet are presented in a fashion without spoiling the aesthetic appeal, and have the first coupling portion formed at one side to hold the targeted element. The first coupling portion has a transverse ridge to form a sliding track to couple with the corner of the target elements. Such a structure also can increase the structural strength and prevent the frame constructed through the posts from tilting.

In principle the first and second coupling portions may be formed in any types of shaped materials presently known. It the invention a T-shaped cross section is selected for the coupling portions to form a closed coupling. Thereby the targeted elements get automatic protection in the upright and longitudinal direction of the posts.

In another embodiment of the invention the side walls of the stacking targeted elements are connected and anchored through corresponding latch notches and lugs. The lugs are held in the notches to form a closed coupling. Hence the side walls of each targeted element have a larger and closed lateral area without transverse support and divided by like elements. As a result, the overall aesthetic appeal of the modular cabinet improves. Moreover, the closed connection of the notches and lugs can further enhance the firmness of the modular cabinet. After the targeted elements have been coupled the side walls form closed and neat lateral areas at the inner side and outer side to make cleaning easier.

In yet another embodiment of the invention the targeted element may have a base board to allow the stacking targeted element to become a box type furniture. In this embodiment the targeted element includes a substantially U-shaped side wall and an entry opening at the front side of the modular cabinet. A closing lid also is provided to seal the entry opening. The closing lid is preferably a pivotal element. To facilitate installation without tools and reducing the number of elements, the base board has a hinge portion to be coupled with an axle of the pivotal element. The base board also has swivel stoppers to control open and closed positions of the pivotal element. The pivotal element may be a drawer or a swivel door.

In one aspect the post has a distal end coupled with a fixing element so that the targeted elements do not slip out through the first coupling portion and can be held securely. As previously discussed, another distal end of the post is coupled with the retaining element. To set the posts at a selected length to be adaptable to different requirements it is preferable to have the two distal ends thereof to be coupled with a corresponding fixing element.

In still another embodiment of the invention the second coupling portion has at least a number of retaining elements to hold the targeted element on the first coupling portion by friction in a closed manner. The retaining element is a clamping element, preferably a clipping element, to be pressed to the post or a side wall of a corresponding targeted element through a fastening element.

In yet another embodiment of the invention each post has at least two or more first coupling portions formed at a selected angle and distance. Thus two targeted elements can be coupled in series longitudinally and vertically on the post, and two neighboring modular cabinets can be coupled at the selected angle and distance.

In yet another aspect the posts are preferably shaped materials made of light metal, especially extruded aluminum (aluminum shaped material). They may be cut to a desired length according to different requirements. The targeted elements and second coupling portion are preferably made from plastics, formed by injection is especially desirable.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1A through 1D, the invention mainly includes a plurality of posts 4 to be disposed at corners of a targeted element (such as a holding rack 5 shown in the drawings). Each diagonal corner 52 of the holding rack 5 has a T-shaped second coupling portion 13 to be held in a first coupling portion 45 of the post 4 in a closed manner. More specifically, the second coupling portion 13 is slidable longitudinally on the post 4 through the first coupling portion 45 and held thereon. By wedging the holding rack 5 through a distal end of the post 4 into the first coupling portion 45, the holding rack 5 can be moved until reaching a desired elevation. As shown in FIG. 1A, the posts 4 are located at the corners of the holding rack 5. They also may be located in the middle portion of side walls 51 of the holding rack 5 (not shown in the drawings). The posts 4 are formed at a length at least the same as the height of the holding rack 5 or multiple times of the minimum height thereof. In addition, the first coupling portion 45 may be formed in a spaced manner in the longitudinal direction of the posts 4. Thereby the holding rack 5 can be engaged with the first coupling portion 45 through the spaced location without through the distal end of the posts 4.

Referring to FIGS. 1B, 1C and 1D, a spacer element 10 may be disposed in the first coupling portion 45 to space the holding rack 5. The spacer element 10 is formed at a length same as the minimum height of the targeted element, and formed in a T-shaped structure to be engaged with the first coupling portion 45. It has a ridge 11 (as shown in FIG. 3B). After the spacer element 10 is disposed in the first coupling portion 45, another holding rack 5 can be mounted through the distal end of the posts 4, referring to FIG. 1C. Such a process can be repeated until a modular cabinet 1 is formed as shown in FIG. 1D. In this embodiment the modular cabinet 1 has four holding racks 5 stacking in a spaced manner in the longitudinal direction of the posts 4 through the spacer element 10 with a same interval space 28 formed between the holding racks 5.

Referring to FIG. 2, the distal end of each post 4 has an axial bore 41 to be coupled with a plugging sleeve 32 to hold a fixing element 35. The plugging sleeve 32 may be coupled with an accessory such as a caster strut 102 which has a shaft 103 and an axle 101 to hold a caster 100, or a pedestal to form a rack modular cabinet. The second coupling portion 13 has a retaining element 16 to form a retaining relationship with the first coupling portion 45. The retaining element 16 may be a clamping element to be fastened to the corner 52 of the holding rack 5 through a fastening element 18 which runs through notches 14 and 15 of the second coupling portion 13 and a connection element 12 thereof. Namely, a frictional force for coupling is generated between the second coupling portion 13 and the first coupling portion 45 through the retaining element 16.

The post 4 also has a jutting plank 42 which has an inner wall with a transverse ridge formed thereon to divide the first coupling portion 45 into a sliding track 46 (referring to FIG. 3A). The spacer element 10 is slidably located on the sliding track 46.

Referring to FIGS. 3A and 3C, the sliding track 46 has a side wall 43 pointing to the targeted element. During wedging the outer wall of the corner 52 is located at an upper distal end of the jutting ridge 42 or the side wall 43 to further strengthen the structure. Through the retaining element 16 the diagonal corner 52 of the holding rack 5 can be clamped firmly at the diagonal position of the sliding track 46 on the post 4 to provide reinforced effect. Such a structure can prevent the structure from tilting. As shown in FIGS. 3A, 3B and 3C, when the second coupling portion 13 is extended from the holding rack 5, the structure previously discussed also can increase the structural strength.

In principle, the retaining element 16 can anchor all the targeted elements to be coupled on the post 4 in a closed manner by friction. In another embodiment of the invention, the interval space 28 is formed through the spacer element 10 (as shown in FIG. 1C) to form a desired positioning at an upper side or lower side thereof.

Referring to FIG. 4, the post 4 may have two jutting planks 42 to form two first coupling portions 45 to hold two neighboring holding racks 5 and form a parallel gap 29. The two jutting planks 42 may also be formed at other angles such as 30 or 45 degrees.
